Systematic noise testing of an enclosed plant with various modifications based on in-situ experimental work,and tests on cooling air intake and exhaust systems,etc,in an acoustic laboratory,a noise level of 70 dB(A) was obtained for the plant.
Methods: Twenty Sprague-Dawley male and female rats, weighing (177 ? 5) g, were divided into 3 groups: normal control group(n = 7) , HBO group (pure oxygen inhalation at 350 kPa for 120 min once daily for 4 d,n = 6), and NTG group (10 mg/kg, sc 3 times a day for 6 d,n = 7).
In this study, 99mTc-HL91 imaging was performed in mice bearing S180 tumor before P-colloid interstitial treatment and some of mice inhaled carbogen gas as a method to solve hypoxia of tumor 32 tissue.
The vacuum negative pressure condition, caused by the operating of inspirator, sucks the air, forms the fine air bubble, diffuse in the water, adhere to the emulsified oil and suspended matters in the water, arrive the water surface together, then achieve the solid-liquid separation.
Primary investigation of the practical applications of the largest value (LV.that was the total amount of diatoms by air-borne and the pollution in the course of wetdigestion) diaton content in lung tissues from non-drowning cadavers in case of drawning diagnosis.
Influence of a lift-engine air intake on the aerodynamic characteristics of a wing
The solutions for flow over nonplanar intersecting surfaces for the cases 0≤γ≤π  and π≤γ≤2π, found in the present study, permit calculation of gasdynamic parameters near a wing with a prismatic appendage (fuselage or air intake).
The study presents a method for construction of solutions in various zones of wing-air intake interaction.
Spread of jet from an annular slit around an air intake
The interference between the shock layer on a cylinder modeling the leading edge of an air intake and an impinging plane inclined shock is investigated experimentally and numerically for a Reynolds number Re0=32.
